Version 0.3.0 has been released.
This fixed the sizing issues while using Gravatars and adds a new Dramatar to the mix.
If you have any issues with it, please let me know.
Morrus: It allows you to use dynamic avatars which are uniquely generated and are each specific to your users.
Best place to demo is on
http://dramatar.com/showme.php which allows you to see the available dramatars, generated for which ever email you enter.
Dramatars are selected based on the email address of your members, but the email itself is not transmitted. Instead a securely generated string is sent which allows the system to select which avatar should be displayed.
